And then the real problem. this does not work. i thought Fn was a valid usage. but it causes the app not to load. i changed it to Hander="getZZZList_selected()" and it works.

note that if i leave out the () and did Handler="getZZZList_selected", it fails. Also, iOS is more tempermental than android so test on iOS. I used a real phone and just kept removing code till it loaded. then it put it back piece by piece till it failed. Note that on android it fails to. Plug in a USB cable and run it via Chrome remote debugging and it works!!!

built the test app best i could but cannot replicate it. something we did is causing it but i don't have an answer now :(
it works though with Handler. probably just JS technicality is causing it based on something in our code.
